You just let Asterisk do the fax detection for you, and when it hears CNG,
send it to the fax extension, and your fax extension would just Dial() one
of the IAXmodems (using IAX)

I second that. After struggling with rxfax (which was total cake to set up,
but reception reliability in my specific installation was poor) I bit the
bullet and put in a separate Hylafax server connected to my Asterisk box
with a crossover cable, rolled up my sleeves, and stated making IAXmodems -
1 per user. I am at over 200 IAXmodem's, and my failure rate on faxes
plummeted to about .8 % - more than comparable to a regular fax machine.
AFAIC, Hylafax + IAXmodem is the way to go for anything serious, unless we
are talking about thousands of users and thousands of faxes per day. I don't
even know what could be scaled to that scenario and not be unmanageable.

For the thousands and thousands scenario you could very well also still 
use HylaFAX (well, HylaFAX+ would probably suit it better) and 
IAXmodem.  However, you'd certainly take advantage of DID and Caller*ID 
support available in both HylaFAX and IAXmodem instead of using a 
one-to-one modem-to-user mapping such as you appear to be doing.

I don't see why rxfax would be less reliable than iaxmodem/hylafax as
it's using the same spandsp to receive fax.

The only difference I can think of is iaxmodem disable V17 reception
within spandsp which is known to be a bit unreliable in reception.
